Answer:

x = 126

Step-by-step explanation:

- $\frac{2}{7}$ x - $\frac{8}{21}$ x + $\frac{1}{3}$ x = -42

- $\frac{2}{7}$ x (multiply numerator and denominator by 3)

- $\frac{6}{21}$ x

$\frac{1}{3}$ x (multiply numerator and denominator by 7)

$\frac{7}{21}$ x

- $\frac{6}{21}$ x - $\frac{8}{21}$ x + $\frac{7}{21}$ x = -42

- $\frac{7}{21}$ x = -42 (multiply everything by -21)

7x = 882 (divide everything by 7)

x = 126

If B is the midpoint of AC, AB = 8x + 5, and BC = 5x2 - 16, then find x and AC

Murljashka [212]

Answer:

Step-by-step explanation:

AB = 8x + 5

BC = 5x² - 16

5x² - 16 = 8x + 5

5x² - 8x - 21 = 0

Quadratic formula

x = [8 ± √(8² – 4·5(-21))] / [2·5]

= [8 ± √484] / 10

= [8 ± 22] /10

= -1.4, 3

-1.4 is an extraneous solution.

x = 3

AB = 8x+5 = 29

AC = 58
